I have a few questions regarding the egr and air injection setup on an 86 22re. I'm currently doing an efi swap on my 87. The motor that was previously in the truck was the 73-84 block with a carb.

I did a complete rebuild on the newer style block in order to do the efi swap. But I'm now seeing I may have to change some egr tubing as well as the air injection. Currently everything on the truck is related to the 73-84 block. I'm now seeing that certain things have changed and will have to be replaced.

currently the air injection tube is the dual style, but from what I can tell that changed from 85+ but I'm having a hard time finding out everything else I will need for the new egr and the rest of the air injection tubing.

can anyone help me out with pictures of diagrams of what I will need to keep it California smog compliant?
